Abstract(s)
The main environmental issue associated with the compost production is the production of a liquid leachate. However, the leachate may also be considered as a source of nutrients and used as fertilizer. The main concern is loading the soil with metals that can result in increased metal content of crops. This work intends to determine the physical and chemical properties of a raw leachate from a mechanical biological treatment plant for municipal solid waste, to assess the possibility of converting it into as commercial fertilizer which meets to the specifications required in the proposal of regulation of the European Parliament of 2016, for fertilizers. In a preliminary study, it is concluded that the leachate qualitatively meets the requirements established for the composition of commercial fertilizers and the production cost of leachate as raw material is low.
